TE offers three types of link boxes with different number of entries to bond the cable sheath to the ground: HVLB-SICO-SLV, HVLB-SICO-GND and HVLB-SICO-CRO. Within the HVLB-SICO-SVL link box, the cable sheath is earthed via a sheath voltage limiter (SVL). The HVLBSICO-GND link box is used to earth the cable sheath direct to the ground without a SVL. Within the HVLB-SICO-CRO link box the cable sheaths are crossbonded.
To get an easy access to the cable sheath for inspections, TE developed a reliable gasket-lid-system, which is tighter against water and dust. The lid system is equipped with a proof device for padlocks to prevent unauthorized access.
A well-arranged configuration ensures a higher reliability. Homogeneous distances between the electrical path, trustworthy electrical connections and a special developed short-circuit-yoke allow a better impulse-voltage and short-circuit withstand. For safety in an unexpected case, our box is tested to absorb the power of an internal arc with 25 kA for 0.1 sec.
